capabilities detection for qemu/kvm bits likely failed. Do you have
kvm and kvm_amd or kvm_intel loaded? Best place to start is checking
/var/log/libvirt/libvirtd.log
Yes, I have the kvm modules loaded and working, but only with new VMs, like I
said above.
Here's what I've found in the logs:

I also noticed that the last two error messages are filling the entire log
file. Any suggestions?
